Currently, after generating run_kselftest.sh, there is no way to choose which test we could run. All the tests are listed together and we have to run all every time. This patch enhanced the run_kselftest.sh to make the tests individually selectable. e.g. $ ./run_kselftest.sh -t "bpf size timers" Before the patch: ================ $ cat run_kselftest.sh \#!/bin/sh BASE_DIR=$(realpath $(dirname $0)) cd $BASE_DIR . ./kselftest/runner.sh ROOT=$PWD if [ "$1" = "--summary" ]; then logfile=$BASE_DIR/output.log cat /dev/null > $logfile fi [ -w /dev/kmsg ] && echo "kselftest: Running tests in android" >> /dev/kmsg cd android run_many \ "run.sh" cd $ROOT ...<snip>... [ -w /dev/kmsg ] && echo "kselftest: Running tests in zram" >> /dev/kmsg cd zram run_many \ "zram.sh" cd $ROOT After the patch: =============== $ cat run_kselftest.sh \#!/bin/sh BASE_DIR=$(realpath $(dirname $0)) . ./kselftest/runner.sh TESTS="android ...<snip>... filesystems/binderfs ...<snip>... zram" run_android() { [ -w /dev/kmsg ] && echo "kselftest: Running tests in android" >> /dev/kmsg cd android run_many \ "run.sh" cd $ROOT } ...<snip>... run_filesystems_binderfs() { [ -w /dev/kmsg ] && echo "kselftest: Running tests in filesystems/binderfs" >> /dev/kmsg cd filesystems/binderfs run_many \ "binderfs_test" cd $ROOT } ...<snip>... run_zram() { [ -w /dev/kmsg ] && echo "kselftest: Running tests in zram" >> /dev/kmsg cd zram run_many \ "zram.sh" cd $ROOT } usage() { cat <<EOF usage: ${0##*/} OPTS -s | --summary Only print summary info and put detailed log in output.log -t | --tests Test name you want to run specifically -h | --help Show this usage info EOF } while true; do case "$1" in -s | --summary ) logfile=$BASE_DIR/output.log; cat /dev/null > $logfile; shift ;; -t | --tests ) TESTS=$2; shift 2 ;; -h | --help ) usage; exit 0;; "" ) break;; * ) usage; exit 1;; esac done cd $BASE_DIR ROOT=$PWD for folder in $TESTS; do folder=$(echo $folder | tr -s '/-' '_') run_$folder done Signed-off-by: Hangbin Liu <liuhangbin@gmail.com> --- v3: 1) rebase the patch to latest code 2) move `tr -s "/-" "_"` to the for loop at the end so user could use test folder name directly. Before the update, user need to run ./run_kselftest.sh -t 'networking_forwarding'. Now they can just run ./run_kselftest.sh -t 'networking/forwarding' directly. v2: update document and commit description. --- Documentation/dev-tools/kselftest.rst | 4 +++ tools/testing/selftests/Makefile | 49 +++++++++++++++++++++------ tools/testing/selftests/lib.mk | 2 +- 3 files changed, 44 insertions(+), 11 deletions(-)
